Rhinitis
Rhinitis is a reaction that happens in the eyes, nose, and throat when allergens in the air trigger the release of histamine in the body. Histamine causes itching, swelling, and fluid to build up in the fragile linings of nasal passages, sinuses, and eyelids.
Raynaud's Phenomenon
Raynaud's phenomenon is a disorder that causes decreased blood flow to the fingers. In some cases, it also causes less blood flow to the ears, toes, nipples, knees, or nose. This happens due to spasms of blood vessels in those areas. The spasms happen in response to cold, stress, or emotional upset.
Reactive Arthritis (Reiter's Syndrome)
Reactive arthritis is a type of arthritis that occurs due to an infection. Arthritis is when joints become inflamed and painful. Reactive arthritis is not contagious. It's also known as Reiter's Syndrome. It mostly affects men ages 20 to 40.
Rheumatic Heart Disease
Rheumatic heart disease is a condition in which the heart valves have been permanently damaged by rheumatic fever. The heart valve damage starts with an untreated or under-treated strep infection. In some cases, strep throat or scarlet fever, which are caused by streptococcus A bacteria, can progress to rheumatic fever if not treated properly.

Refractive Errors
Astigmatism is one type of refractive error. It's a condition in which an abnormal curvature of the cornea can cause two focal points to fall in two different locations—making objects up close and at a distance appear blurry.
